header() clarification

JMJimmy

I was just writing a page up and came across what to me appears to be a bug but it could be the proper behaviour...

//in a file somewhere:

function somefunction(){
  echo "Hi";
}

//then on the actual page:

include("somefunction.php");
if($this){
  header("Location: here");
} else {
  somefunction();
}

Now - this generates an error saying I've already sent header information but I it's an either or thing.

Is this a bug? Odd behaviour? just plain annoying?

Ok, I can't tell by looking at your code. (your comments make it ambiguous). You can't send anything as output before you send your header().

you can if you turn output_buffering on in php.ini (php 4.x +)

but I don't reccommend it.

If you are sure your code is not outputting anything, check for any white space before the opening <?php tag. White space will output as HTML and generate the 'Headers already sent' error.

Almost certainly some whitespace somewhere, make usre you don't have a rouge extra line or space after your closing ?>
